I think there's a problem with the system iu of my samsung A20s phone. It doesn't open easily, i need to wait for few seconds before it opens, sometimes a minute. At first it's not like that. I wonder why? And what happened?
Check if there's an open apps. Try clear it all with recent apps button. Then also try Go to Settings, Device Care, and tap "Optimize now". If the problem still persists, try restart the phone.
